NEWAYGO, MI – The examination of the body of Shannon Marie Siders continues this week and authorities say they could be that much closer to solving the young woman’s 1989 homicide.

Michigan State Police Detective Lt. Cameron Henke, commander of the Sixth District Special Investigation section, said that Siders body remains under the examination of Dr. Norman Sauer, forensic anthropologist from Michigan State University, and Dr. Brian Hunter, a pathologist from Lansing,

The task force was assembled in September, 2011 by Michigan State Police
investigators and includes the Newaygo County Sheriff's Office,
Newaygo City Police Department and Newaygo County Prosecutor Robert
Springstead.

They are confident the exhumation could lead to some substantial information to help them solve her case.

Siders, then 18, was last seen alive on July 18, 1989. Her badly decomposed body was found on Oct. 15, 1989, in the Manistee National Forest off M-82 and Thornapple Road in Newaygo County's Brooks Township.

As of Wednesday, authorities haven't publicly identified any persons of interests or suspects in the case.

However, Henke said they have received a number of tips over the years.

The exhumation on July 26 was the first time ever a body has been exhumed from the Newaygo cemetery as part of a criminal investigation, Henke had said.

Siders’ father, Robert Siders, of Newaygo, was there during the exhumation, as well as a man who had been dating Shannon Siders when she had gone missing.

Authorities hope they continue to receive tips about the decades-old murder.
